Product Description



*** You Cannot Just Install a Metal Gear Without Also Changing The Motor To The GruvenParts INTERNALLY GROUNDED MOTOR !  You Will Short Out the Body Control Module.  All Of Our Kits Come With New Motors Which Are Internally Grounded and Work With Metal Gears - So Don't Just Replace the Gear, You Must Replace Both Gear AND Motor When Going to Metal !!! ***




 ** Click HERE for the NEW GruvenParts Installation Video **

** Click HERE for the Mirror Gear DIY Article for Full Size GM Trucks **  or (Download PDF)

** Click HERE for the Traverse/Acadia/Outlook Supplemental Instructions **


** 2 Options Are Now Available ***

Note that if you chose Option 2, you will either need to send in your unit for repair directly, or wait approximately 2 months for us to get a unit to repair.  These are becoming hard to find and people arent returning their cores as often anymore for some reason.  We can usually repair sent in units same day to minimize down time as you cant install the mirror without the drive unit in place.

Option 1: 

Buy strengthened brass gears pre-mounted to a new machined steel main spiral shaft + hi-torque motor in quantity 1 set for 1 mirror or 2 sets for 2 mirrors ($64.99 / $99.99).  

Option 2:

Buy a rebuilt complete motor drive unit with new hi-torque motor and brass gear pre-installed and tested ($229.99 minus $30 core return = $199.99).  Please note when buying the complete drive unit, you must choose passenger side or drivers side, and there is a $30 core refund so be sure to send back your old assembly in repairable condition.  Core returns are only applicable to complete drive units and when you are ready to return your core, please email for instructions.  Your CORE must be rebuildable.  We cannot accept units which have parts other than the motor/spur gear broken as cores as we would have no way to rebuild them.

***** PLEASE NOTE WHEN ORDERING THE COMPLETE DRIVE UNIT - If you are in a hurry for this, its best to check with us to see if we have any cores.  It could be 4-6 weeks to receive this, based on how many units we have in the shop.  People do not send back their cores very quickly, so we are usually waiting.  You can send in your own unit to be worked as well, and we will apply the $30 core when you send in and try to work it same day or very quick.  We are currently on a 2 Month Back Order Unless You Can Send In Your Unit to be Rebuilt


Other Parts Available :

We also carry a limited number of used parts to service these mirrors in case you loose or break something.  We have some of everything, so just email if you need something.  We do now have some used mirror glass drive units for both sides - these are the little motorized units that actually adjust the angle of the mirror glass.


** Product Description ** is pleased to announce replacement strengthened BRASS spur gears and high torque INTERNALLY GROUNDED motors (OEM MOTOR WONT WORK WITH METAL) for the power folding mirrors on 2007-2014 GM trucks including Acadia, Traverse, Enclave, Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali.  Also fits ALL 2007-Present GMC pick-up trucks. As many have discovered, the folding mirror assembly on these trucks suffers from a thin, weak, plastic spur gear mounted to the main drive shaft.  The plastic spur gear cracks at the slightest impact or just wears out over time causing an inoperable folding mirror.  The GM motors also get weak and die quickly. Unfortunately, GM will only sell you a complete folding mirror assembly, which will cost you from $700-$1,200 ea after labor and paint, depending on the year/make/model.  And that $ would be wasted on another mirror assembly with another weak, plastic spur gear and weak electric motor that will also soon fail.  Don't waste time or hard earned money on more GM parts that will also soon fail! has addressed this issue by designing a strengthened spur gear made from solid gear BRASS with a thicker cross section to eliminate the stress concentrations which cause fatigue cracking in the GM plastic gear. We have also designed a replacement high torque electric motor to accompany this new metal gear. Our new electric motor is required when switching out to the metal gear, as the ground circuit in the OEM motor does not allow for a metal gear to be installed. You can chose to buy the gear/motor combo for one or both sides with the spur gear pre-attached to a new main shaft or you can buy complete drive units which are rebuilt and already have the new metal gears and hi torque motor installed in them.  

We have thoroughly tested our redesigned spur gear and high torque motor using a new, OEM mirror assembly and computerized test equipment.  Our test samples barely showed any wear whatsoever, and the testing did include random wacks against the mirror, jamming the mirror operation as it was folding, and manually stressing the mechanism all in an attempt the break the gear.  Each sample was tested more than 5,000 open/close cycles and was still going strong at that point !  

This product carries a LIFETIME WARRANTY!  Provided you don't burn the vehicle, or otherwise smash the mirror into something, you can send back the motor drive unit to us and we'll replace the gear assembly and get it working again free of charge.  You would only be responsible for shipping under this warranty.

  1. Never Again! 5 Star Review

    Posted by on 12th Feb 2022

    Using the Gruven gears and motor, this customer will NEVER need to deal with the mirror problem again! Your directions posted on line are excellent. Thank You.

  2. Resolution to GM 's poor design 5 Star Review

    Posted by on 31st Jan 2022

    Straight forward video instruction on dis -assembly and install.
    So far they close and open much faster than the old working one.
    hope the quality is there to support the price since i tend to keep my vehicles for a long time.

  3. Excellent ! 5 Star Review

    Posted by on 26th Jan 2022

    Thanks to the gear and motor kits from Gruven Parts and their instruction video I was able to fix the mirrors on a 2008 Yukon Denali.
    Use the right tools, follow the video directions and be patient, you will fix yours.
    1- You will need a vise with minimum 5 inch jaw opening.
    2- A 15/16 socket and a washer with same diameter as the socket.
    3- Align one of the corners of the socket with the protrusions in the big gear base and use the washer on the jaw side to allow the socket to turn easily.

  4. Great product! 5 Star Review

    Posted by on 21st Jan 2022

    Parts are quality, customer service is fantastic, and the install video for the replacement motor and metal spur gear for the folding mirror is spot on! I used it to remove the old product, and it was a great resource to make sure I put everything back properly!

  5. awesome upgrade 5 Star Review

    Posted by on 7th Jan 2022

    The improved spur gear and motor worked like a charm. The online video was a great help. Thanks to Paul for his help. It was a great experience with Gruven parts. Highly recommend. Thanks

  6. Nice solid product 4 Star Review

    Posted by on 5th Jan 2022

    Great improvement over original equipment.
    Just wished it was a bit quieter.

  7. works like a charm 5 Star Review

    Purchased motor for my side folding mirrors on my GMC truck. Solved non folding mirror issue. Issue resolved.

  8. '09 2500 HD. Seemed simple enough... And it was. 5 Star Review

    Posted by on 14th Dec 2021

    I'd already taken the driver's mirror off once to make sure the gears were the problem so getting things apart again was easy. Passenger side motor housing was a little tough open once off the truck, but not a surprise for a 13 year old component exposed to the elements.
    Instructions and video were fantastic guides. Doing both mirrors took less than 2 hours.

  9. excellent 5 Star Review

    Posted by on 12th Dec 2021

    Fit perfect on Cadillac Escalade

  10. No more floppy mirror on my '11 Sierra! 5 Star Review

    Posted by on 6th Dec 2021

    The gear in my power folding mirror assembly broke quite a while ago, and I have been dealing with zip ties, Gorilla tape, and a fair amount of swearing. I ordered gears and motors for both sides, figured the passenger side one would break eventually. I wouldn't call installing these parts an easy job, but with the straightforward instructions and the excellent YouTube video, I think just about anyone should be able to do it. Outstanding quality parts, thanks!
